FIG. 12 is a T applied as a transmission control procedure executed when an audiovisual terminal such as a video conference communication terminal apparatus transmits data using the B channel.
TC standard JT-H. 242 shows an example of a general procedure of 242. In this case, an example of a transmission procedure for exchanging audio data, general-purpose data, and moving image data between terminals using two B channels is shown.

First, the calling terminal makes a call to the destination terminal and performs a call setup procedure on the D channel to secure one B channel (hereinafter referred to as the first channel) (Phase A). Frame synchronization is performed while exchanging frame data in which PCM voice data (A-law or μ-law, 64 Kbps) is set on one channel (frame mode), and when frame synchronization is established, mutual capability BAS
Data and command BAS data are exchanged (phase B1-1), the transmission mode to be used at that time is determined, and an additional call setup request for securing the second B channel is started (phase B1-2). ).

Then, in principle, the modes having the highest functions common to each other are selected from the contents of the exchange of the transmission modes at that time (phase B1-3), and the calling terminal receives the selected operation mode. A BAS command specifying the receiving function of the terminal is transmitted to the calling terminal so that the receiving function is operated. In this case, if a BAS command in a mode different from the BAS command transmitted by the calling terminal is received, the BAS command is received. Send the BAS command again, match the send mode to the receive mode, and send the BAS command specifying the terminal function to operate the function to the called terminal,
Parameters common to the device functions of the calling terminal and the called terminal are set (phase B2). Thereby, in the first channel, for example, data transmission of audio data (16 Kbps) and data transmission of moving image data (46.4 Kbps) corresponding to the transmission mode selected at that time are performed (phase C). .

When the first channel starts data transmission in the frame mode, the call setup procedure is performed on the second B channel (hereinafter referred to as the second channel) on the D channel (phase CA), and the second channel is established. Then, frame data including only the frame synchronization signal FAS and the bit allocation signal BAS is exchanged using the second channel to establish frame synchronization and multi-frame synchronization (phase CB1-11), and then the first channel and the second channel. Synchronization between channels is established (phase CB1-12).

When the synchronization of the two B channels is completed, a BAS command is sent from the calling terminal side to set the transmission mode (phase CB1-2), and the transmission mode is switched to the set contents (phase CB1-3). ), And setting common parameters (phase CB2). The sent BA
When a BAS command in a mode different from the S command is received, the received BAS command is transmitted again, the transmission mode is switched so that the transmission mode matches the reception mode, and common parameters are set.

In this way, when the initialization of the second channel is completed, after that, two pieces of frame data exchanged in the first channel and two pieces of frame data exchanged in the second channel are synchronized with each other. Using the B channel, for example, voice data, general data, and
Video data is 56 Kbps and 6.4 Kbps, respectively
And a data rate of 62.4 Kbps is assigned for data transmission (see FIG. 13). Here, the general-purpose data channel is used for exchanging data for the conference control function, the telewriting communication function, and the bulk transfer function (group 4 facsimile data, etc.), for example.

To end such data transmission, first, the second channel is disconnected. At this time, the first
For voice data transmission on the channel only, the procedure for setting the common mode is performed (Phase CD
1), the mode of the second channel is switched to the mode 0F of the frame mode (phase CD2). At this time, the first channel and the second channel are asynchronous, and the second channel is in a state in which the call is held in the transmission state of only the frame synchronization signal FAS and the bit allocation signal BAS, and the call of the D channel is disconnected. The call for the second channel can be released by the release procedure.

In the first channel, phase CD1
During and during the phase CD2, the audio data is transmitted at the transmission rate of 56 Kbps in the frame mode, the transmission of the moving image data is stopped, and when the operator of one terminal ends the call, the mode is switched to the mode 0F (phase D2. ) After that, the call of the first channel can be released by the call disconnection release procedure of the D channel.

As a result, the call disconnection release procedure is executed on the D channel for the first channel and the second channel (phase E), and the audiovisual transmission between the two terminals ends.

As described above, in an audiovisual terminal such as a video conference communication terminal device, one B channel (first channel) is first secured and a frame mode is established, and then audio data and a moving image are transmitted on this first channel. If the second B channel (second channel) can be set at the same time while allocating the data transmission rate and performing the data transmission in the transient mode, the second channel is set by the D channel call setup procedure. Secure. Then, the first channel transmitting in the transient mode and the newly secured second channel are channel-synchronized, and when the channel synchronization is established, the allocation of the transmission rate of the audio data and the moving image data is reset. However, by utilizing the increased transmission capacity of the B channel, higher quality audio data and moving image data can be exchanged.

Further, when the data transmission is completed, it is necessary to once change the mode in which the transmission path in which both the first channel and the second channel are synchronized is used to the mode in which only the first channel is used. is there. Therefore, first, each encoding rule of audio data and moving image data is set to a method that optimizes the transmission capacity of the first channel of 62.4 Kbps, and the transmission mode of only the first channel is changed, while the second channel is , The state of synchronization with the first channel is stopped, the mode shifts to mode 0F in which user data is in an idle transmission state, and the call is disconnected / released by the call disconnection release procedure of the D channel. The first channel is
From two types of media transmission of audio data and video data,
After changing to mode 0F, which is a transmission mode for only voice data, the call is disconnected / released by the D channel call disconnection release procedure.
release. In addition, the first channel, without switching the mode to two types of media transmission of audio data and video data,
It is also possible to disconnect / release the call after directly changing the mode to the mode 0F. In addition, the billing information obtained in the call disconnection / release procedure is managed for each channel.

When the user makes a request for help display, the video conference communication terminal device of the present embodiment displays the help request count (use count) for each application and the execution state. A history is formed and stored in the help statistics table as shown in FIG.

Here, the items of the help statistics table are the application name, the application ID (identification number) set in the application, the execution state when the help display is requested, the type of help data, and

It consists of a telephone number (ISDN address) set in the user device, a temporary area for storing the latest received help statistics table, and a history area for storing information summarizing all received help statistics tables.

In this way, since the center apparatus can know the help display request status in a large number of user apparatuses, the user handles the provision order of displaying the help data based on the information. Since the situation can be adjusted to be easier, the usability of the help function of the application can be improved, for example, when the version of the application is upgraded.

In addition to the order in which the help data is displayed, the help data can be subdivided or the help data can be integrated, and the usability of the help function in the application can be further improved.

FIG. 16 shows an example of a process executed when a help display is requested by the user device and the help display is completed.

Further, the user device can display the help statistical data at the request of the user, and an example of processing at that time is shown in FIG.

When the user issues a display request for help statistical data (decision 201 is YES), it is checked whether or not one or more help statistical data are stored in the help statistical data table (decision 202). Judgment 202
When the result is YES, the display data for listing the contents of the help statistical data table is formed (process 2).
03), the list display is output to the liquid crystal display device 10 (process 204).

In this state, the process waits until the user gives an instruction to end the display (NO loop of decision 205). If the user gives an instruction to end the display and the result of decision 205 is YES, the liquid crystal display device 10 displays the result. The list display that has been displayed is terminated (process 206), and this process is terminated.

When the help statistical data is not stored in the help statistical data table and the result of judgment 202 is NO, a guidance message indicating that there is no help statistical data is displayed on the liquid crystal display device 10. (Process 207) and this process ends.

Based on the contents of the help statistical data table received at that time (process 613), the contents of the user help statistical data corresponding to the user device which is the calling terminal at that time (the contents of the "calling number" information element Judgment) is updated (process 614) and this process ends.

By the way, in each of the above-mentioned embodiments, the help statistical table as shown in FIG. 14 is formed as the history information of the help statistical data. For example, in order to explain the contents of the operation guidance information of the apparatus. When collecting only the help information of the above, a help statistical table as shown in FIG. 25 may be formed.

Here, the items of the help statistics table are the application name, the application ID (identification number) set in the application, the type of operation guidance information displayed when the help display is requested,
It also consists of the number of times help was used.

In this case, since the center device can know the request status of the help display for each operation guidance information in a large number of user devices, the content of the operation guidance information can be known based on the information. It is possible to predict whether or not it is difficult, and thereby, the content of the operation guidance information can be made more familiar. Further, when the content of the operation guidance information is improved in this way, finally, it becomes unnecessary to present the help information for the operation guidance information, and as a result, the data amount of the help information can be reduced. it can. In recent years, since the operation content of the device has become complicated, the data amount of help information tends to become huge, and it is preferable that the help information can be reduced by improving the content of the operation guidance information in this way.
